With the popularity of the Internet, email has become an indispensable communication tool in people's daily life and work. How to receive external emails on your own website has become a problem that website developers need to face.

IMAP (Internet Mail Access Protocol) protocol is a standard protocol for receiving email. The function of receiving external emails can be easily implemented using the IMAP protocol in PHP.

1. Preparation

Before using PHP to receive emails, you need to make sure that your server has the IMAP extension enabled. You can check whether the IMAP extension is supported through the phpinfo() function. If it is not enabled, you need to remove the previous comment in the php.ini file and restart the server.

For example, the php.ini file under Windows:

extension=php_imap.dll
Copy after login

2. Connect to the mailbox server

To use the IMAP protocol to receive mail, you need to establish a connection with the mailbox server first. In PHP, you can use the imap_open() function to establish a connection with the server. The format is as follows:

imap_open($mailbox, $username, $password);
Copy after login

Among them, $mailbox represents the email server address and port, $username represents the email account, and $password represents the email password.

Example:

$mailbox = "{imap.gmail.com:993/imap/ssl}INBOX";
$username = "example@gmail.com";
$password = "password";
$con = imap_open($mailbox, $username, $password);
Copy after login

Among them, $mailbox represents the server address and port connecting to Gmail. Gmail uses SSL connection, so /imap/ssl needs to be added after the port number. $username and $password represent the Gmail account and password respectively.

3. Select the email folder

After the connection is successful, you need to select the email folder to receive. In PHP, you can use the imap_reopen() function or the imap_select() function to select a mail folder.

For example, before selecting the inbox folder, you can use the following code to select the mail folder:

$folder = "INBOX";
imap_reopen($con, $mailbox . $folder);
Copy after login

Among them, $folder represents the name of the folder to be selected, which can be the inbox (INBOX), Drafts, Sent, etc.

4. Get mail

After selecting the mail folder, you can get the mail. In PHP, you can use the imap_search() function to search for emails and the imap_fetchbody() function to get the email content. For example:

//搜索收件箱并获取邮件号码
$emails = imap_search($con, 'ALL');
if($emails) {
    //将最新邮件排在最前面
    rsort($emails);
    foreach($emails as $email_number) {
        //获取邮件标题
        $overview = imap_fetch_overview($con, $email_number, 0);
        $subject = isset($overview[0]->subject) ? $overview[0]->subject : '';
        //获取邮件内容
        $message = imap_fetchbody($con, $email_number, 1);
    }
}
Copy after login

5. Close the connection

Finally, use the imap_close() function to close the connection:

imap_close($con);
Copy after login

The above is how to use PHP to receive external emails. With the help of the IMAP protocol, you can easily implement the function of receiving external emails on your own website, providing more convenient services for website users.
